In this case I think you have mislabed a trojan with a rootkit. You should determine (if possible) what rootkit has infected the machine. It sounds like a new variant or perhaps a new tool altogether. I would suggest wiping the box and rebuilding it if you cannot determine exactly what is the culprit or any way to clean it. To answer your questions: 1. No, I have not seen this in our nets. 2. I answered this above. 3. Probably not. There is nothing law enforcement can do unless there is a substantial loss. You are ultimately responsible for what gets installed on your machines regardless of the method of installation. Now, if you find someone using data that you can prove could only have been acquired by this method, then you should discuss with your legal department about your options and what you will need to do to provide proof of this infringment.

-----Original Message----- From: listbounce () securityfocus com [mailto:listbounce () securityfocus com] On Behalf Of Goetz, Richard Sent: Tuesday, October 24, 2006 8:54 AM To: incidents () securityfocus com Subject: Malware/trojan attacks Over the last several months we have on more than one occasion uncovered a number of Trojans that appear to be seeking corporate information, sending that over a chat session to/through several European sites and downloading additional programs to the infected computer. Here's a short synopsis of the type of conversations one of our people uncovered on a laptop on the network: Contacts 203.121.73.136 on port TCP/17555. IRC commands were sent to the workstation to run a command "staticftp" 70.84.109.84 to download a program x.exe. Instructed to launch 5 scans (netapi on port 137, wkssvc port 445, asn on port 445, dcom on port 135 and lsass on port 445). Connects to 66.36.243.116 on TCP/80 and starts a PHP-based conversation, giving the workstation credentials to the host and receiving the following information: CARGO:smtp_purple; MOD:smtp; PATH:http://niuqennaois.com/s2.5.exe; SERVER:209.160.64.216; REFRESH:2700;KEY:864a1bae77fc8053055d02550ed7b49c; Connects to 195.49.141.23 on TCP/3144, retrieving unreadable data Connects to 66.36.243.116 on TCP/80, exchanging credentials via PHP: To host: uuid <wsname>_547611528 wv mag5_min0_build2195_Service_Pack_4 cargo check purple To workstation: REFRESH:3600; KEY: 864a1bae77fc8053055d02550ed7b49c; HTTP connections are made to 66.45.232.66, 66.36.243.116 to perform similar PHP and download conversations. Three way TCP handshakes are attempted to 74.52.53.66, 68.142.212.41and 68.142.212.93 on TCP/80, but no further conversation was made. My questions are: 1. Are other folks in the community seeing this kind of activity? 2. What, aside from deleting what you can find what other actions are recommended/required? Who, if anyone, in the community or law enforcement should be notified? If this post should be somewhere else, please let me know.
